Hello everyone,

not sure if it is still possible to proceed in this topic, but I am facing a similar problem: would like to embed larger payloads (greater 3M) as presentedForm in a DiagnosticReport to send it to our archive server (have to prepend as well, unfortunately I am not too familiar with FHIR at all).

My brute force method is to populate a HS.FHIR.DTL.vR4.Model.Resource.DiagnosticReport using a DTL, convert it to a DynamicObject, replace the presentedForm.data-Property with the large file stream, and write it out to a QuickStream:

ClassMethod GetQuickStreamFromDiagnosticReport(pDiagRep As HS.FHIR.DTL.vR4.Model.Resource.DiagnosticReport, pFile As %String) As %String
{
    #dim tStreamInFile As %Stream.FileBinary
    #dim tTempJSON As %Stream.Object
    #dim tDynOb As %DynamicObject
    #dim tQuickStream As HS.SDA3.QuickStream
    
    Set tStreamInFile = ##class(%Stream.FileBinary).%New()
    Do tStreamInFile.FilenameSet(pFile)
    
    // convert: DiagnosticReport --> JSON --> DynamicObject
     Set tTempJSON = pDiagRep.ToJSON()
     Set tDynOb = ##class(%DynamicAbstractObject).%FromJSON(tTempJSON)
     
     // replace presentedForm.(1).data-property by stream
     Do tDynOb.%Get("presentedForm").%Get(0).%Set("data", tStreamInFile, "stream")
    
    // serialize DynamicObject
    Set tQuickStream = ##class(HS.SDA3.QuickStream).%New()
    Do tDynOb.%ToJSON(tQuickStream)
    Do tQuickStream.%Save()
    
    
    Quit tQuickStream.%Id()
}

It works, although it seems like a hack. Any hints how to improve would be highly appreciated...

Thanks!

Hi all,

I am facing actually a similar issue, any hint would be highly appreciated: I developed an operation that downloads a document (from a REST Service as well) and stores it to a local folder on the server. If saving locally fails, e.g. due to insufficient file permissions, the .stream-files do remain in the stream-folder for the namespace. 

Before using the Save-Method in %FileBinaryStream, the payload is copied from HttpResponse.Data (CopyFrom).

I purged the trigger-messages for the operation as well, but without an effect. Can I simply delete those .stream-files? Maybe they were created temporarily before trying to copy them into the mentioned directory, or as a backup? Is there any way how to check if they are related to any database objects?

Thanks!
